BuddyPress.org

I want to extend my buddypress installation to allow three types of registrations ( author, contributor and sponsors) using the buddypress member type.

I need to allow frontend posting of contents (ideas and project) through the buddypress activity page with a toggle button which enables
photo, video attachments,
and details of
their ideas and category selections enabled (only author member types can do this).

sponsors and contributors on the other hand, views, subscribe and supports the idea. (“subscribe to this” replaces the favorite/like button)

I found I plugin which might help me. https://wordpress.org/plugins/user-submitted-posts/
